Do WiFi digital photo frames use a lot of electricity?

Most consume 5-15 watts, comparable to a phone charger. Frames with motion sensors (like Nixplay) use even less since they sleep when no one is nearby. Annual electricity cost is typically under $10.

Can multiple people send photos to the same frame?

Yes. All major WiFi frames support multiple senders. Aura and Nixplay use their apps to invite family members. Skylight lets anyone with the frame's email address send photos. There is no practical limit on the number of senders.
